Army Mortar Team Engages Taliban
Panjwai District, Kandahar, Afghanistan - After Taliban fighters fire on a U.S. Army patrol, a mortar team begins dropping 60mm mortars on the wood line where the fighters were spotted. "Charge Zero" mentioned in the video, refers to all extra charges being removed from the base of the mortar round due to the short distance. You can see the number two removing the charges from the base of the round before handing it to the number one.
